After Acquired Spouses of U Visa Applicants can apply for their U Visas:

U Visa Applicants can file U-2 Visa petitions for their spouses who they marry AFTER their U Visa petitions have been filed if they are married at the time the principal U Visa petition is approved (adjudicated favorably), rather than when the principal petition was filed. USCIS has adopted the decision issued by the Ninth Circuit in Medina Tovar v. Zuchowski for nationwide application.
